Eavesdropping

Eavesdropping is simply the act of listening in on a conversation over the network from your mobile phone.

There are two purposes for scanning:

1. Eavesdropping.

Using an OKI described earlier, you will need to do the following:

Power on phone and immediately hold 7 + 9 at the same time while it boots up for about two seconds.

Release 7 + 9 and hit Menu, Send, End, Recall, Store, Clear and the phone should read good timing!!!

If all goes well hit 1 + 3 at the same time to clear the prompt.

Now hit #12 SND to recieve audio.

Then hit #77 SND and you should hear a buzzing noise because you have just enabled the loud speaker.

Ok, now to begin the scanning of channels enter the following command:

#73AAAABBBBCC SND AAAA = 4 digit low channel number (Channel to begin scan on) BBBB = 4 digit high channel (Cell Channel to end scan on) CC = 2 digit number for how many seconds to scan each channel

For example if you want to scan channels 50-300 at a 1 second interval you would enter:

#730050030001 SND and your scan should begin.

Press # when you find a channel with someone talking you want to listen to and press # again to resume scanning. Press * to restart the scan.

Now if you only want to listen to a specific channel on a lower volume just enter this instead:


#12 SND
#76 SND to turn the receiver on
#09<channel number>SND to select channel you want to listen on.


2. Snatching Pairs.

Now sometimes you will come across a channel that is widely described as 'Hornets/Bees Buzzing'. This is the encoded ESN/MIN pair. The OKI series described has a headphone jack so you can plug this into your computer to record and decode.

If you wish to build some devices that can scan the airwaves there is a book out by the author Rudolf F. "Rudy" Graham, called the Encyclopedia of Electronic Projects, Vol 7. Has everything you would want to know about electronic serveilence EXCEPT the holy grail, GSM Intercepting.
